Many serious accidents have happened in the world where systems have been large-scale
and complex, and have caused heavy damage and a social sense of instability …

Most engineering systems su? er some deterioration with time from wear,-tigue, and
damage, and ultimately fail when their strength exceeds a critical level. Failure mechanisms …

Reliability theory is a major concern for engineers and managers engaged in making high
quality products and designing highly reliable systems.“Advanced Reliability Models and …

Some systems work for a job with random working times. It would be useful for such systems
that they are checked at the completion of working times to detect their failures, which is …

In this paper, we consider two kinds of sequential checkpoint placement problems with
infinite/finite time horizon. For these problems, we apply approximation methods based on …

In the present paper, we investigate a preventive replacement policy based on multiple
attributes. A system is subject to two types of shocks which arrive according to a non …

This paper censiders an extended cumulative damage model with two kindsof shocks: One
is failureshock at which a system failsand the other isdarnageshock at which itsuffers only …

This paper examines comprehensive evaluation of aperiodic time-based checkpointing and
rejuvenation schemes maximizing the steady-state system availability in an operational …

When the data of a database are frequently updated, the operation of incremental or
cumulative backup is usually adopted so as to make the backup copies efficiently. Such …

Dr. Shunji Osaki is an internationally recognized researcher in the field of system reliability
engineering spanning over four decades. In 2001–2011, he worked in Nanzan University …
